I don't think they are in Iraq for the resources, not even slightly.
Even if they got control of that area and were able to begin operations of extracting whatever resources, how expensive would it be to ship USA contract workers and supplies over there and then ship the product all the way back.
If they were wanting to take control of the resources over there, wouldn't it make more sense to just have the iraqi people excavate it and just buy it from Iraq??
Or enslave the iraqi people to ship it to the USA for free under the threat of violence. This seems to be what they are good at, so that would seem like the predictable plan.
I could be missing something, but I cannot see any logical reason for USA to care about taking over their resources.
